The are is A=W*L
The perimeter is P=2L+2W
So there is some form of relationship.
A/W=L and P-2W=2L
A/W=L and (P-2W)/2=L
A/W=(P-2W)/2
2A/W=P-2W
2A=PW-2W^2
If you line them up according to the quadratic formula you can have
2W^2-PW+2A=0 where W is the variable equivalent to X in normal circumstances and P and A are set values. There is always a relationship between two numbers, or at least you can almost always create your own relationship. This may seem rather complicated but this is a complicated question and I applaud you for asking something of this sort.
Answer:
X = 13
X = 70
Step-by-step explanation:
1. Since it is a right angle set the equation up as X +2 + 75 = 90.
X =13
2. Set up x - 20 + 40 = 90 since right triangles are 90 degrees
x = 70
Answer:
-7, -0
Step-by-step explanation:
Х - has Danny
2 - has Carly

9 - have together
x + 2 = 9
x = 9 - 2
x = 7 - has Carly.
